Know before you buy
The M50 is specifically engineered for measurement, offering an exceptionally flat frequency response from 3 Hz to 50 kHz. Unlike standard studio mics, it is designed to capture acoustic data with high precision and minimal coloration, ensuring your calibration software receives the most accurate information possible.
While the M50 is primarily a measurement tool, its high SPL handling and fast transient response make it capable of capturing instruments with extreme detail. However, keep in mind that its omnidirectional pattern will capture a significant amount of room sound, which may not be ideal for all recording scenarios.
The M50 requires standard 48V phantom power, which is provided by most professional audio interfaces, mixers, and preamps. No specialized power supply is needed, but you will need a standard XLR cable to connect it to your interface.
The extended frequency range allows for a more detailed analysis of high-frequency transients and phase accuracy. This is particularly useful when tuning high-end sound systems or performing research where capturing ultrasonic information is necessary for a complete acoustic profile.
Yes, the M50 features a robust solid-state design built to withstand demanding environments. It also includes a protective wood box, which provides a secure way to store and transport the microphone between job sites.
